BRlCK-MAKING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 272,224, dated February13, 1883.

Application filed August 5, 1882.

' To all whom it may concern:

Be it known that I, Mronanr. FITZPATRICK, of St. Louis, Missouri, haveinvented a new and useful Improvement in Brick-Making Mae chines, ofwhich the following is a clear, full,

and exact description, reierenco being had to the accompanying drawings,making a part of this specification, in which- Figure l is a perspectiveviewof a brickmaking machine with my improvements attached. Fig. 2 is aplan view of the same. Fig. 3 is a side elevation. Fig. 4. is alongitudinal section on line was of Fig. 2. Fig. 5 is a horizontalsection'on line 2 z of Fig. Fig. 6 is a horizontal section on line 00 mof Fig. 3.

' My invention relates to machines for pressing bricks from clay; and itconsists of the several combinations ofdevices hereinafter explained andclaimed.

To enable others skilled in the art to make and use my inventioml willproceed to de-.

erated by the drum a having its bearings bej tween two of the pillars A,and the drum a having its bearings in the frame-work A. This drum isoperated by means of the belt B, connecting the shaft of the drum withthe main shaft of the machine. Over the table A I place the revolvingtable B, secured on the vvertical shaft B which passes. through the 4.0table A and rests in a shoe at its lower end, secured to the frame-workA. On this same shaft, and below table A is rigidly secured the metalplate B. This plate is provided on its upper surface with four verticalpins, 1). 5 Againstthe said pins operates the notched pawl b, which isconnected by the shalt b to a. reciprocating arm, b operated by thecocentric O, attached to the driving-shaft 0. It is evident that therevolution of the drivingshaft and its eccentric will, through theconnection named, operate the pawl'b, drawing it hinges and allows thebrick to pass down,and as (NO model.)

back until the notch catches in a pin. b, and then forcing it forward,thereby causing a partial revolution of the vertical shalt B and with itthe revolving table B, which is rigidly 5 secured to the upper end ofthe vertical shaft. Through this revolving table are formed openings ormolds c, in which to press and form bricks. As the table revolves theseopenings are brou gh t in turn under the hopper G which is provided withslides c for the purpose of regulating the amount of material enteringthe molds. 7

0n the lower face of the revolving table B, and immediately under themolds, I. attach hinged bottoms m, which drop and rise as they pass theopenings in the lower table, where the bricks make their exit. The objct of these hinged bottoms is to catch and hold the bricks while beingpressed, and by remaining under the bricks until they reach theexit-opening in thelower table preventany loose clay t'rom getingbetween the tables. When the exit-opening is reached the movable bottomdrops on its the revolving table continues to move it the bottom isagain lifted up to its place, and is closed against the bottom of themold. These bottoms may also be used for regulating the thickness of thebrick by adding a plate of any desired thickness to the upper face ofthe hinged bottom, and which will fit snugly in the mold as the bottomis raised. The thickness of the brick may be in this way regulated atpleasure, and on the plate may be placed letters, figures, or othercharacters for the purpose of stamping them on the brick.

,On the rear end of frame A is secured the lever D on rock-shaft D andprovided with the plunger-s cl d, which enter the molds 0 simultaneouslyon the opposite sides of the revolving table. Theplunger (Z enters themold for the purpose of pressing the brick into shape, and the plunger ddescends into the mold to force the brick from the mold as the hingedbottom drops. After the plunger d has entered the mold cit is forceddown by thetrip-hammer D. The handle of this hammer is rigidly securedto the rock-shaft D having its hearings in the frame A. On the handle ofthe hammer is attached the vertical pin d which is brought intocontactwith the cam E,

which is rigidly secured on the driving-shaft 0. By the revolution ofthe cam acting upon the pin a the hammer D is caused to rise and at theproper moment to fall upon the plunger (7, thus securing the fall of thehammer on the plunger (1, pressing the brick in the mold 0. The upperportion of the hammer D is made hollow for the reception of additionalweights for the purpose of adjusting the force of the hammer. Theseadditional or extra weights may he held in position by a bolt passingthrough the hollow portion of the hammer. The rock-shalt D by means ofthe cam E, causes the arm E to vibrate, and this vibration, by means ofthe connecting-rods e, alternately operates the slide a in the hopperand allows the necessary feed to the molds. One end of the rock-shaft,to which the lever Dis rigidly secured, is provided with the arm E forthe purpose of operating the shaft and lifting the lever. This arm iscontrolled by the cocentric G, secured to the main driving-shalt 0,operating through the connecting-rod H and supplementary pivoted rod H,as shown in Fig. 3.

Through the revolving table B is formed a slot, 1, through which Iintroduce a scraper for the purpose of scraping and cleaning the lowertable, A when necessary to remove any clay therefrom. A stop-brake maybe applied to the revolving table, so as to bring the molds directlyunder the flanges.

Having thus described my invention, what Iclaim as new, and desire tosecure by Letters Patent, is

1. In a brick-molding machine, the revolving table 13, provided withopenings or molds c, in combination with the table A, provided with theopening a, the plate B provided with the pin I), and notched pawl 11,all constructed to operate substantially as and for the purposedescribrd. v

2. The levolvingtable B, provided with the openings or molds c, incombination with the hinged bottoms at, substantially as and for thepurpose set forth.

3. The revolving table 13, provided with openings or molds c, incombination with the lever 1). provided with the plungers d 41,substantially as and for the purpose set forth.

4. The lever D, carrying the plungers d (1, in combination with thetrip-hammer D, substantially as and for the purpose set forth.

5. The lever D, naming the plungers d d, in combination with thetrip-hammer D and shaft (3, provided with the cam E, substantially asand for the purpose set forth.

6. The shaft O, can; inc; the eccentric Grand the rods H H, incombination with the rockshaft provided with the arm 1') and lever D,carrying; the plungers d (1, whereby the lever and plnngers are raisedand lowered, substantially as hert-in described.

7. The rockshatt D carrying the arm E, iu combination with the rods 0and slides 0, substantially as and for the purpose set forth.
